No tsunami threat after 5.3-magnitude quake off Big Island

A 5.3-magnitude earthquake struck off the southeast coast of the Big Island at around 2:15 p.m. Tuesday, according to the U.S. Geological Survey, and the Pacific Tsunami Warning Center says there is no threat of a tsunami.

The earthquake epicenter was about 55 miles south of Hilo at a depth of 25.4 miles.

The magnitude was initially estimated at 5.6, but more detailed seismic analyses resulted in the final magnitude of 5.3.

A woman in the Kaumana City subdivision said her entire house shook with pictures falling to the ground and her cat fell to the floor.

The woman said the quake lasted about 40 seconds.

Hawaii County Civil Defense Director Darryl Oliveira says there are no immediate reports of damage.

The earthquake was widely felt on the Island of Hawaii, with a few felt reports from as far away as Oahu. The USGS "Did you feel it?" website received more than 400 felt reports within the first hour of the earthquake.

Kevin Dayton, the executive assistant to the mayor, says he felt a large jolt in the county building in Hilo. Tony Andrade, a stock clerk at the Mizuno Superette grocery store in Pahala, says the shelves rocked but nothing fell off.
